I finally put my Lance Camper on the Dodge for the first time. I have the Firestone Airbags and the camper weighs about 3400 pounds with water and propane. Still some "stuff" to go in the camper before heading out camping for the first time this summer.

What is good starting point for the pressure in the airbags with the camper on my stock '07 Quad Cab Dually?

It's pretty much a personal preference thing. Airbags can't raise the legal weight carrying ability of the truck. Start with minimal air in the bags and look at the stance of the truck. Take it for a drive. If it's sagged in the rear, try 30 or so psi in the bags. Increase pressure until the rear isn't sagged anymore and doesn't feel like it's bottoming out on every little bump.

I had a slide in that weighed about the same as your Lance. I would put 70 lbs. in the bags. Firestone says you can go all the way up to 100 lbs.

Utundra

Thanks. I started at 50 lbs and it seemed a little mushy. I'll give 70 a try.

In addition to vehicle stance, I would see how it rides. I was under-pressurizing my bags at ~20psi. I would hit bumps in the road, and bottom out the suspension. I was also riding on the overload springs.

I figure to keep ~50-80psi with the camper on. That range seems to provide the best ride. The airbags keep the suspension in it's normal travel range so the springs and shocks can work together to dampen side-side and front-back motion.

I have an Arctic Fox 990, weighs 5k fully loaded. I have Timbrens and overload bump stop spacers. With air bags, everyone's air pressure will vary as each truck/camper combo is different, and you will want to keep your overload springs engaged for the additional stability they will provide with the top heavy load of a camper. I've made my own 2" spacers that work really well. You can also look into the Tork Lift Stable Loads at Tork Lifts website.With the spacers/Stable Loads installed adjust your air pressure so that the overloads are just engaged which really helps with the sway. When the truck is empty the overloads are not touching so your empty ride remains the same. Also check out rv.net/camper section, and there is a ton of information there on setting up your truck/camper.

In addition to what RWitt suggested,

I took a tape measure and measured for the ground to the bottom lip of the rear wheel when empty. I load my Lance 835 and car hauler and load all of the contents. I then re-measure again at the same spot and fill my airbags to get back to the empty measurement or slightly lower. I usually end end up around 60 Lbs give or take

I started at 50 PSI and there was at least an inch between the overloads and the bracket. I dropped it down to 16 psi before the overloads are engaged. Seems a little low, but I did not take it for a spin yet. I'll throw the Viair compressor in before heading out tomorrow. It is only a 150 mile trip to the camp site.

Go to this site http://http://www.torklift.com/p.php?w_page=stableload for the stable loads or at this link http://http://www.rv.net/forum/index...d/20048392.cfm for the bump stop extensions for your overloads. This will get your ride height back up and you'll have much more stability. Both of these spacers are about 1 to 1.5" away from your overloads when empty so your unloaded ride is not affected.

had almost the same set up on my first dodge. . . .never even measured pressure. Park on a flat and pump it to the desired ride height. Worked great and took out lot's of body roll too.
